Description

Technical Field

[0001] This utility model relates to the field of coffee brewing, and in particular to a cup warmer and a coffee machine. Background Technology

[0002] In today's coffee-loving society, whether for everyday home use or in commercial settings, people have high expectations for the taste and quality of coffee. However, temperature management of the coffee beverage after brewing has become a key pain point affecting the drinking experience. Currently, most coffee machines only have basic brewing functions and cannot effectively heat the coffee cup and coffee, causing the brewed coffee to cool down very quickly, seriously affecting its flavor and taste. Utility Model Content

[0003] Therefore, it is necessary to provide a cup warmer and a coffee machine to address the problem that coffee machines cannot heat coffee cups and coffee.

[0004] A cup warmer includes: a housing assembly having a brewing chamber and a heating chamber, the heating chamber being adjacent to the top wall of the housing assembly; a heating assembly disposed on the housing assembly and located within the heating chamber; a brewing assembly disposed on the housing assembly and located within the brewing chamber, the brewing assembly being in communication with the heating assembly; and a liquid supply assembly disposed on the housing assembly and in communication with the heating assembly.

[0005] The cup warming device disclosed in this application has a heating chamber adjacent to the top wall of the housing assembly, which can effectively conduct the heat generated by the heating component to the top of the housing assembly. Users can preheat the cup by placing it on the top wall of the housing assembly. A warm cup reduces the rapid heat loss after pouring coffee, keeping the coffee at a suitable drinking temperature for a longer period. A warm cup locks in the aroma and rich flavor of the coffee, preventing it from becoming bland due to a sudden drop in temperature, thus improving the overall quality and drinking experience. The cup warming device is simple and intuitive to operate; the function automatically activates when the user starts the coffee machine to brew coffee, requiring no additional operation. Placing the coffee cup simply requires placing it stably on the top wall of the housing assembly; for home users or coffee shop staff, there is virtually no operational barrier. Warming the cup simultaneously with coffee preparation simplifies the entire coffee-making process, saving time and effort and improving ease of use. The cup warming device integrates the cup warming and coffee brewing functions into the same housing assembly, cleverly achieving the cup warming function without increasing the device's footprint by utilizing the structure of the heating chamber adjacent to the top wall. Compared to standalone cup warmers, this integrated design saves counter space in kitchens or coffee shops, making it especially suitable for space-constrained environments. Furthermore, the compact layout of the internal components, with the brewing, heating, and liquid supply units interconnected, shortens the liquid and heat transfer path, improving operating efficiency and reducing energy consumption.

[0006] In one embodiment, the heating chamber is arranged adjacent to the brewing chamber. This adjacent arrangement significantly shortens the distance the heat generated by the heating element travels to the brewing chamber. The adjacent layout reduces the heat transfer path within the housing assembly, minimizing heat loss during transmission. During coffee making, the heat generated by the heating element can be conducted to the brewing chamber more quickly, effectively drying the chamber and ensuring its dryness.

[0007] In one embodiment, the portion of the top wall of the housing assembly opposite the heating cavity is planar. This planar structure increases the contact area between the top wall of the housing assembly and the heating cavity, allowing heat generated by the heating component to be transferred to the top wall more quickly and evenly. Compared to a non-planar structure, the planar design reduces obstacles in the heat transfer process, lowers thermal resistance, and improves heat conduction efficiency.

[0008] In one embodiment, the housing assembly includes a supporting housing, a heating chamber housing, and a cover. The heating chamber housing is disposed on the supporting housing, and the heating chamber housing and the supporting housing enclose the brewing chamber. The heating chamber housing has the heating chamber, the brewing assembly is disposed on the supporting housing, and the cover is disposed on the supporting housing, with the cover opposite to the brewing chamber and the heating chamber. The brewing chamber formed by the heating chamber housing and the supporting housing provides a stable installation space for the brewing assembly, enabling precise positioning and stable operation. Simultaneously, the heating chamber housing itself has a heating chamber, providing dedicated space for the heating assembly and preventing interference between different functional components. This rational division of functional areas fully utilizes the internal space of the housing assembly, making the internal structure of the coffee machine compact and orderly, achieving efficient coffee making within a limited space.

[0009] In one embodiment, the heating assembly includes a mounting housing and a heating element. The mounting housing is disposed on the housing assembly and located within the heating chamber, with the mounting housing positioned on the side of the heating chamber closest to the brewing chamber. By positioning the mounting housing within the heating chamber and close to the brewing chamber, the distance the heat generated by the heating element travels to the brewing assembly is significantly shortened. Because the mounting housing is close to the brewing chamber, the heat generated by the heating element can act more directly on the brewing assembly. The mounting housing securely positions the heating element within the heating chamber, providing a stable operating environment for the heating element.

[0010] In one embodiment, there are multiple heating components, all disposed on the housing assembly and located within the heating cavity. The simultaneous operation of multiple heating components provides multiple heat sources to the heating cavity, enabling rapid temperature increases. Each heating component's power can be independently controlled, and the coordinated adjustment of multiple components by the control system achieves various functions.

[0011] A coffee machine, comprising:

[0012] The aforementioned cup warmer;

[0013] A liquid dispensing assembly is disposed on the cup warmer;

[0014] The water circuit assembly is connected to both the liquid dispensing assembly and the brewing assembly.

[0015] The coffee machine disclosed in this application features a cup warmer whose heating element provides a stable heat source for the brewing element, ensuring precise water temperature. Combined with the water flow component's stable water transmission, this allows for even extraction of coffee grounds during brewing. The dispensing component precisely controls the dispensing volume and flow rate, guaranteeing consistent concentration and flavor in every cup of coffee. The preheating function further reduces heat loss, locking in aroma and taste, allowing the coffee to fully express its optimal flavor, whether making a rich and full-bodied espresso or a crisp and refreshing Americano.

[0016] In one embodiment, the liquid supply assembly includes a water tank, a flow meter, and a water pump, with the water tank, flow meter, water pump, and heating assembly connected in sequence. The flow meter allows for real-time monitoring and precise measurement of the liquid flow rate. During coffee preparation, the flow meter can precisely control the amount of water entering the heating assembly according to a preset program or user requirements. When making a standard espresso, the flow meter accurately controls the amount of water entering the heating assembly, ensuring accurate coffee extraction ratios and preventing the coffee's taste and quality from being affected by too much or too little water. Combined with the dispensing assembly and water circuit assembly, precise control is achieved throughout the entire process from water supply to dispensing, meeting the stringent water volume requirements of different coffee preparation processes. The water pump provides stable power for liquid delivery, ensuring a continuous and stable flow of water from the tank to the heating assembly. The water pump employs a constant pressure design, maintaining a stable flow rate and pressure under different water level conditions, preventing fluctuations in the heating efficiency of the heating assembly or poor extraction results due to unstable water flow. When making multiple cups of coffee in a row, the water pump works continuously and stably to ensure a stable water supply for each cup of coffee, thus improving the consistency and stability of coffee making.

[0017] In one embodiment, a first one-way valve is also included, which is connected to both the heating component and the brewing component. By installing the first one-way valve between the heating component and the brewing component, the liquid flow direction can be strictly controlled, allowing liquid to flow only from the heating component to the brewing component, preventing liquid in the brewing component from flowing back to the heating component. During the coffee brewing process, when the pressure inside the brewing component changes, such as a brief pressure fluctuation or a pressure drop after brewing, the first one-way valve will automatically close, preventing brewed coffee or residual water from flowing back into the heating component. This avoids coffee contamination of the heating component's interior, prevents scale and coffee residue from accumulating in the heating chamber, reduces the difficulty of cleaning the equipment, and extends the service life of the heating component.

[0018] In one embodiment, the water circuit assembly includes a second one-way valve, which is connected to both the brewing assembly and the dispensing assembly. By positioning the second one-way valve between the brewing and dispensing assemblies, liquid flow is strictly limited to the dispensing assembly, effectively preventing reverse flow. After coffee brewing, the pressure inside the brewing assembly decreases, and the second one-way valve automatically closes, preventing residual liquid or external impurities in the dispensing assembly from flowing back into the brewing assembly. This avoids secondary contamination of the coffee grounds inside the brewing assembly, prevents bacterial growth in residual liquid, ensures that the coffee grounds used for each brewing are clean, and guarantees that the coffee quality is not affected.

[0019] In one embodiment, the system further includes a first one-way valve, a first solenoid valve, and a steam valve. The first one-way valve is connected to both the heating element and the brewing element, and the first solenoid valve is connected to both the heating element and the steam valve. By connecting the first one-way valve to both the heating element and the brewing element, the first one-way valve ensures that liquid flows only from the heating element to the brewing element, preventing liquid or coffee residue in the brewing element from flowing back to the heating element. The first solenoid valve, connected to both the heating element and the steam valve, precisely controls the flow and on / off of steam. When the user needs to use the steam function to make milk foam or heat a beverage, the first solenoid valve opens, allowing steam generated by the heating element to flow smoothly to the steam valve and be discharged through it. When the steam is used up, the first solenoid valve quickly closes, cutting off the steam passage and preventing steam leakage or backflow. This precise flow control ensures that steam is output only when needed, improving steam utilization efficiency, avoiding energy waste, and ensuring user safety.

[0020] In one embodiment, the heating assembly includes a first heating element and a second heating element. A first one-way valve is connected to both the first heating element and the brewing assembly. The first heating element, the first solenoid valve, the second heating element, and the steam valve are sequentially connected. The first solenoid valve, connected to the heating assembly and the steam valve, allows for precise control of the steam flow and its on / off state. When the user needs to use the steam function to make milk foam or heat beverages, the first solenoid valve opens, allowing the steam generated by the heating element to flow smoothly to the steam valve and be discharged through it. When the steam is used up, the first solenoid valve quickly closes, cutting off the steam passage and preventing steam leakage or backflow. This precise flow control ensures that steam is output only when needed, improving steam utilization efficiency, avoiding energy waste, and ensuring user safety.

[0021] In one embodiment, the heating assembly includes a first heating element and a second heating element, and a second solenoid valve. The first one-way valve is connected to both the first heating element and the brewing assembly. The first heating element, the second solenoid valve, the second heating element, and a steam valve are sequentially connected. The second solenoid valve is connected to a hot water pipe. The assembly also includes a cooling module and a pressure relief module, with the cooling module connected to both the first solenoid valve and the pressure relief module. By controlling the operating states of the first and second heating elements, multiple heating modes can be achieved. When only coffee brewing is needed, the first heating element can be turned on alone to quickly heat the water to the brewing temperature. When the steam function is needed, the second heating element is turned on to generate steam. If both coffee brewing and steam use are required simultaneously, both heating elements can operate concurrently. This flexible heating mode switching meets the diverse coffee-making needs of users, easily handling single-origin coffee, espresso, and specialty coffees with milk foam. The cooling module cools the gas generated when the pressure is too high and outputs it to the pressure relief module. Attached Figure Description

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] The following describes some embodiments of the cup warmer and coffee machine according to the present invention with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 1 to 7 As shown, this embodiment discloses a cup warmer, including: a shell assembly 1, which has a brewing chamber 101 and a heating chamber 102, the heating chamber 102 being adjacent to the top wall of the shell assembly 1; a heating assembly 2, which is disposed on the shell assembly 1 and located within the heating chamber 102; a brewing assembly 3, which is disposed on the shell assembly 1 and located within the brewing chamber 101, and is connected to the heating assembly 2; and a liquid supply assembly 4, which is disposed on the shell assembly 1 and is connected to the heating assembly 2.

[0042] The cup warming device disclosed in this application has a heating chamber 102 adjacent to the top wall of the housing assembly 1, which can effectively conduct the heat generated by the heating component 2 to the top of the housing assembly 1. The user can preheat the cup by placing it on the top wall of the housing assembly 1. A warm cup reduces the rapid heat loss after pouring coffee, keeping the coffee at a suitable drinking temperature for a longer period. A warm cup locks in the aroma and rich flavor of the coffee, preventing it from becoming bland due to a sudden drop in temperature, thus improving the overall quality and drinking experience. The cup warming device is simple and intuitive to operate; the function automatically activates when the user starts the coffee machine to brew coffee, requiring no additional operation. Placing the coffee cup simply requires placing it stably on the top wall of the housing assembly 1, making it virtually inaccessible to home users or coffee shop staff. Warming the cup simultaneously with coffee preparation simplifies the entire coffee-making process, saves time and effort, and enhances ease of use. The cup warmer integrates cup warming and coffee brewing functions into a single housing component 1. Utilizing the structure of the heating chamber 102 adjacent to the top wall, it cleverly achieves cup warming without increasing the device's floor space. Compared to standalone cup warmers, this integrated design saves counter space in kitchens or coffee shops, making it particularly suitable for space-constrained environments. Furthermore, the compact layout of the internal components—brewing component 3, heating component 2, and liquid supply component 4—is interconnected, shortening the liquid and heat transfer path, improving operating efficiency, and reducing energy consumption.

[0043] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the heating chamber 102 and the brewing chamber 101 are arranged adjacent to each other. By arranging the heating chamber 102 and the brewing chamber 101 adjacently, the distance that the heat generated by the heating component 2 is transferred to the brewing chamber 101 is significantly shortened. The adjacent arrangement reduces the heat transfer path within the housing assembly 1, reducing heat loss during transmission. During coffee making, the heat generated by the heating component 2 can be conducted to the brewing chamber 101 more quickly, drying the brewing chamber 101 and ensuring its dryness.

[0044] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the portion of the top wall of the housing assembly 1 that is opposite to the heating cavity 102 is a plane. The planar structure increases the contact area between the top wall of the housing assembly 1 and the heating cavity 102, allowing the heat generated by the heating assembly 2 to be transferred to the top wall more quickly and evenly. Compared to a non-planar structure, the planar design reduces obstacles in the heat transfer process, lowers thermal resistance, and improves heat conduction efficiency.

[0045] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a supporting housing 11, a heating chamber housing 12, and a cover 13. The heating chamber housing 12 is disposed on the supporting housing 11, and the heating chamber housing 12 and the supporting housing 11 enclose a brewing chamber 101. The heating chamber housing 12 has a heating chamber 102. The brewing assembly 3 is disposed on the supporting housing 11, and the cover 13 covers the supporting housing 11, with the cover 13 opposite to the brewing chamber 101 and the heating chamber 102. By enclosing the brewing chamber 101 with the supporting housing 11, the heating chamber housing 12 provides a stable installation space for the brewing assembly 3, enabling it to be accurately positioned and operate stably. At the same time, the heating chamber housing 12 itself has a heating chamber 102, providing dedicated space for the heating assembly 2 and avoiding mutual interference between different functional components. This reasonable division of functional areas makes full use of the internal space of the housing assembly 1, making the internal structure of the coffee machine compact and orderly, and achieving efficient coffee making within a limited space.

[0046] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the heating assembly 2 includes a mounting housing 21 and a heating element 22. The mounting housing 21 is disposed on the housing assembly 1 and located within the heating chamber 102, with the mounting housing 21 positioned on the side of the heating chamber 102 closest to the brewing chamber 101. By placing the mounting housing 21 within the heating chamber 102 and close to the brewing chamber 101, the distance that the heat generated by the heating element 22 needs to be transferred to the brewing assembly 3 is greatly shortened. Because the mounting housing 21 is close to the brewing chamber 101, the heat generated by the heating element 22 can act more directly on the brewing assembly 3. The mounting housing 21 securely houses the heating element 22 within the heating chamber 102, providing a stable working environment for the heating element 22.

[0047] like Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of heating components 2 is multiple, and the multiple heating components 2 are all disposed on the housing assembly 1 and located inside the heating cavity 102. By having multiple heating components 2 work simultaneously, it is equivalent to providing multiple heat sources for the heating cavity 102, which can quickly increase the temperature inside the cavity. The power of each heating component 2 can be independently controlled, and various different functions can be achieved through the coordinated adjustment of multiple components by the control system.

[0048] Example 2

[0049] like Figures 1 to 2 As shown, this embodiment discloses a coffee machine, including:

[0050] The aforementioned cup warmer 100;

[0051] Liquid dispensing component 200 is mounted on cup warmer 100;

[0052] Water circuit component 300 is connected to liquid outlet component 200 and brewing component 3 respectively.

[0053] The coffee machine disclosed in this application features a cup warmer 100 whose heating element 2 provides a stable heat source for the brewing element 3, ensuring precise water temperature. Combined with the stable water flow transmission of the water path element 300, this allows for even extraction of coffee grounds during brewing. The dispensing element 200 precisely controls the dispensing volume and flow rate, ensuring consistent concentration and flavor in every cup of coffee. The preheating function further reduces heat loss from the coffee, locking in aroma and taste, allowing the coffee to fully express its optimal flavor, whether making a rich and full-bodied espresso or a crisp and refreshing Americano.

[0054] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the liquid supply component 4 includes a water tank 41, a flow meter 42, and a water pump 43, and the water tank 41, flow meter 42, water pump 43, and heating component 2 are connected in sequence. The flow meter 42 can monitor and accurately measure the flow rate of the liquid in real time. During coffee making, the flow meter 42 can precisely control the amount of water entering the heating component 2 according to a preset program or user requirements. When making a standard espresso, the flow meter 42 can accurately control the amount of water entering the heating component 2, ensuring accurate coffee extraction ratio and avoiding the impact of too much or too little water on the taste and quality of the coffee. Combined with the liquid outlet component 200 and the water circuit component 300, precise control of the entire process from water supply to liquid outlet is achieved, meeting the strict requirements of different coffee making processes for water volume. The water pump 43 provides stable power for liquid delivery, ensuring that the water in the water tank 41 can continuously and stably flow to the heating component 2. The water pump 43 adopts a constant pressure design, which can maintain a stable flow rate and pressure under different water level conditions, avoiding fluctuations in the heating efficiency of the heating component 2 or poor extraction effect of the brewing component 3 due to unstable water flow. When making multiple cups of coffee continuously, the water pump 43 works steadily to ensure a stable water supply for each cup of coffee, improving the consistency and stability of coffee making.

[0055] In addition to the features of the above embodiments, this embodiment further includes a first one-way valve, which is connected to both the heating assembly 2 and the brewing assembly 3. By installing the first one-way valve between the heating assembly 2 and the brewing assembly 3, the liquid flow direction can be strictly controlled, allowing liquid to flow only from the heating assembly 2 to the brewing assembly 3, preventing liquid in the brewing assembly 3 from flowing back to the heating assembly 2. During the coffee brewing process, when the pressure inside the brewing assembly 3 changes, such as a brief pressure fluctuation or a pressure drop after brewing, the first one-way valve will automatically close, preventing brewed coffee liquid or residual water from flowing back to the heating assembly 2. This avoids coffee liquid contaminating the interior of the heating assembly 2, prevents scale and coffee residue from accumulating in the heating chamber 102, reduces the difficulty of cleaning the equipment, and extends the service life of the heating assembly 2.

[0056] In addition to the features of the above embodiments, this embodiment further specifies that: the water circuit assembly 300 includes a second one-way valve, which is connected to both the brewing assembly 3 and the dispensing assembly 200. By positioning the second one-way valve between the brewing assembly 3 and the dispensing assembly 200, liquid is strictly limited to flow only from the brewing assembly 3 to the dispensing assembly 200, effectively preventing reverse flow. After coffee brewing is complete, the pressure inside the brewing assembly 3 decreases, and the second one-way valve automatically closes, preventing residual liquid or external impurities in the dispensing assembly 200 from flowing back into the brewing assembly 3. This avoids secondary contamination of the coffee powder inside the brewing assembly 3, prevents bacterial growth in residual liquid, ensures that the coffee powder used for each brewing is clean, and guarantees that the coffee quality is not affected.

[0057] In addition to the features of the above embodiments, this embodiment further includes a first one-way valve, a first solenoid valve, and a steam valve. The first one-way valve is connected to both the heating assembly 2 and the brewing assembly 3, and the first solenoid valve is connected to both the heating assembly 2 and the steam valve. By connecting the first one-way valve to both the heating assembly 2 and the brewing assembly 3, the first one-way valve ensures that liquid can only flow from the heating assembly 2 to the brewing assembly 3, preventing liquid or coffee residue in the brewing assembly 3 from flowing back to the heating assembly 2. The first solenoid valve, connected to both the heating assembly 2 and the steam valve, can precisely control the flow direction and on / off state of steam. When the user needs to use the steam function to make milk foam or heat beverages, the first solenoid valve opens, allowing the steam generated by the heating assembly 2 to flow smoothly to the steam valve and be discharged through it. When the steam is used up, the first solenoid valve quickly closes, cutting off the steam passage and preventing steam leakage or backflow. This precise flow control ensures that steam is output only when needed, improving steam utilization efficiency, avoiding energy waste, and ensuring user safety.

[0058] In addition to the features of the above embodiments, this embodiment further specifies that: the heating component 2 includes a first heating element 23 and a second heating element 24, and a first one-way valve is connected to the first heating element 23 and the brewing component 3 respectively. The first heating element 23, the first solenoid valve, the second heating element 24, and the steam valve are connected in sequence. Through the connection of the first solenoid valve with the heating component 2 and the steam valve, the flow direction and on / off state of steam can be precisely controlled. When the user needs to use the steam function to make milk foam or heat beverages, the first solenoid valve opens, allowing the steam generated by the heating component 2 to flow smoothly to the steam valve and be discharged through it; when the steam is used up, the first solenoid valve quickly closes, cutting off the steam passage and preventing steam leakage or backflow. This precise flow control ensures that steam is output only when needed, improving steam utilization efficiency, avoiding energy waste, and ensuring user safety.

[0059] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heating component 2 includes a first heating element 23 and a second heating element 24, and also includes a second solenoid valve. A first one-way valve is connected to the first heating element 23 and the brewing component 3 respectively. The first heating element 23, the second solenoid valve, the first solenoid valve, the second heating element 24, and the steam valve are connected in sequence. The second solenoid valve is connected to the hot water pipe. It also includes a cooling module and a pressure relief module. The cooling module is connected to the first solenoid valve and the pressure relief module respectively. By controlling the working state of the first heating element 23 and the second heating element 24, multiple heating modes can be realized. When only coffee brewing is needed, the first heating element 23 can be turned on alone to quickly heat the water to the brewing temperature; when the steam function is needed, the second heating element 24 is turned on to generate steam; if both coffee brewing and steam use are needed simultaneously, the two heating elements can work at the same time. This flexible switching of heating modes meets the diverse coffee making needs of users, whether it is making single-origin coffee, espresso, or specialty coffee with milk foam, it can easily handle it. The cooling module is designed to cool the gas generated when the pressure is too high before outputting it to the pressure relief module.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
